During the last few decades, many different oscillator models and analysis techniques have been presented. From the negative impedance model, cavity type and DROs to the general feedback type, all oscillators have one common property. They are nonlinea...

Generally, an oscillator can be seen as a positive feedback system. It usually consists of an amplifier followed by a resonator, which is fed back to the amplifier input, as shown in Figure 1 . The amplifier task is to compensate for the losses in the resonator, and the...
